I have a 1099-NEC and when I try to finish and file, it brings up a box about my schedule C but no matter what number i put in it, it doesn’t fix the issue. What do I do?

I don’t want to have to mail my taxes but this site isn’t letting me do anything else. There is no box on mine tax return about a schedule C and I already read that TurboTax is supposed to automatically fill in your schedule C. I don’t understand what issue is.
